G'day, My results are:
Source - XG1, RX gain calibration per the utility routine: Subsequently: Main RX only, pre amp OFF - 50uV (S9), 1uV (S2) Sub-RX ON therefore splitter loss: Main RX S8 & S1 Sub-RX S7 & S0 No big deal but not identical. As a matter of interest, the S-meter on the main RX had been set up a year ago or more as above. When I checked it before doing the RX gain calibration I discovered that the 1uV and 50uV figures were S5 & S9. Little wonder I thought the local noise level had been creeping up! Maybe after playing with the AGC parameters a re-cal of the S-meter is required, maybe not, but something altered it. I assume that given the 50uV S9 setting was correct then it isn't associated with the XG1.
